Hello and welcome! My name isCustomerand I can assist you with your question. Do the headlights work? What about the dome lights? Can I start by getting your VIN? Thank you!
Customer: replied 1 year ago.
no headlights ! total disconnect of electric power ! I found some fuse links all look good and fuses are also good . on left side by the ABS is a junction box with a red wire . I put jumper cable to it and all power came on so the disconnect must be before it ! i'm wondering if there's a fuse link hidden I wire harness or the neutral safety switch could disconnect power ?????

Yes there is. I suspect you have a bad battery, a battery low on a charge or a bad connection at or after the battery. If you send me your vin I can provide you with a wiring diagram of the power distribution circuit which will help pinpoint the root cause.

The battery is good . checked all connections to engine and body grounds ! put jumper cables to my battery and put positive to the junction box on left side next to ABS controller. there's a large red wire feeding that junction and when I put power to it I got power to everything , so the disconnect has to be before there. fuse links on positive an negative cables all appear good ! There must be a fuse link in the dash or under the hood hidden in the wiring harness ? Or I burnt a switch out somewhere ??? on a 97 blazer*****, last 8 of vin V2 122954

I checked the fuse links on battery cables and appear good but will check to see if power is going thru them!!!!!!
